It was discovered by American astronomer Marc Buie at Kitt Peak Observatory on 7 November 2002. The primary measures approximately 324 km mi off 3 us in diameter. The object belongs to the cold classical population and is a binary. Satellite The companion was discovered by Keith Noll, Will Grundy, Susan Benecchi, and Hal Levison using Hubble Space Telescope on 21 September 2008. The discovery was announced on 24 September 2009. The moon's apparent separation from the primary was 3026 90 km with an orbital period of 30.7615 0.0064 days. Physical characteristics The estimated combined size of 2002 VT 130 is about 324 57 68 km. Johnston's Archive estimates a mean diameter of 251 km for the primary, and 205 km for the satellite based on a secondary-to-primary diameter ratio of 0.817. 2002 VT 130 shows significant photometric variability with a lightcurve amplitude of 0.21 magnitudes, which indicates one of its components has an elongated shape.
